Title: Connector for single mode optical fiber
Inventor: ISHIZUKA SATOSHI
IPC: G02B6/32
Filed: 1985-02-14
Abstract: PURPOSE:To obtain an optical connector where the exact precision of individual parts constituting the connector is unnecessary, by bringing closely a spherical lens, which has the same diameters as a single mode optical fiber strand and has the focus on the surface of the lens itself, into contact with the end face of this strand. CONSTITUTION:Since the exit light of the single mode optical fiber can be regarded as a spot light source because its core diameter is 6-10mu, a spherical lens 10 which has the focus on the surface of the lens itself is formed to have the same diameter as a strand 1 and is inserted in to a through hole 12 holding the strand 1 and is brought closely into contact with the end face of the strand 1 so that the optical axis of the lens 10 and that of the strand 1 coincide with each other. Then, high-precision positioning is made unnecessary. If an adhesive having a refractive index approximately equal to that of the core of the strand is used for junction between the lens 10 and the strand 1, it is sufficient if the end face of the stand 1 is cut by a fiber cutter, and polishing of the end face is unnecessary, and the light reflected back from the end face of the strand 1 is reduced. Thus, the connector for single mode optical fiber is obtained easily.

Title: Clock with countdown display
Inventor: YOSHIDA TATSUHIRO
IPC: G04B19/00
Filed: 1990-02-06
Abstract: PURPOSE:To make it possible to know the number of remaining days to a desired event at all times by having a countdown mechanism and by gearing it to a hand-operating mechanism which lessens the numeral displayed in a remaining days display window by one for every 24 hours. CONSTITUTION:A remaining days display window 6 is formed in a dial plate 3 of the main body 1 of a clock, and the display window 6 is so constructed that a numerical value of thousands, for instance, can be displayed therein digitally. A crown 7 for remaining days sets the numeral displayed in the display window 6 at a desired numerical value. The numerical value displayed in this display window 6 is lessened by one for every 24 hours in gearing with an operation of a driving mechanism of the clock. When the numerical value in the display window 6 is set at the number of remaining days to the scheduled day of an event by operating the crown 7, the numeral displayed in the display window 6 is lessened by one for every 24 hours in gearing with a mechanism operating a hand 5, and therefore the owner of the clock can know the number of remaining days accurately.

IPC: B23K35/30
Filed: 1985-02-14
Abstract: PURPOSE:To improve the strength characteristic of a weld metal and to prevent the cracking thereof by welding different metals such as stainless steel, carbon steel and low alloy steel by using a low carbon welding material contg. specific wt% of Cr, Ni, Nb, Ti, Al, etc. CONSTITUTION:0.5-4% Ni, 1-8% Cr, 0.02-2% Si, 0.02-2% Mn, 0.05-4% Nb+Ta, 0.05-0.4% Al, <=1.5% Ti, <=2% Mo and <=0.06% C are incorporated as the components of the welding material into said material and the balance is composed of Fe. A base metal 1 which is stainless steel or special alloy such as HK-40 and the carbon steel or low alloy metal 2 are welded by using such welding material to form the weld metal 3. Since the content of Cr of the weld metal 3 decreases, the decarburization and carburization near the low alloy steel side bond are decreased, the hardness change is decreased and the difference in the coefft. of thermal expansion is lessened as well. The cracking is thus prevented and the creep strength characteristic, etc. are improved.

Title: Pressure casting device
Inventor: HAMAMURO NAOJI
IPC: B22D39/06
Filed: 1981-02-26
Abstract: PURPOSE:To stabilize casting conditions in the stage of supplying molten lead from a lead melting pan, pressurizing a pressurizing pot in a closed state and injection-casting a grid body, by providing a level sensor between the melting pan and a supply pipe and controlling the level of the molten lead by this. CONSTITUTION:Molten lead 3 is supplied from a lead melting pan 1 through a molten lead supply valve 4 to a lead melting auxiliary pan 5 and a pressurizing pot 9, then the level 16 of the molten lead ascends. Next, when the lead level 16 arrives at the specified level, a level sensor 17 operates, and the valve 4 cooperating with this closes thereby stopping the supply of the lead 3. Thence, in this state the inside of the pot 9 is pressurized and the lead 3 is injected into dies 13. When the lead level 16 lowers upon injection of the lead 3, a sensor 17 operates to supply the lead 3, by which the level 16 is maintained constant and the stable casting conditions are obtained.

Title: Method and apparatus for measuring horizontal position of tunnel excavating machine
Inventor: UMETSU TAKAO
IPC: G01V15/00
Filed: 1983-02-21
Abstract: PURPOSE:To make it possible to measure the horizontal position of an excavating machine even though an obstructing substance is located at a directly upper part of an element, by providing the magnetic-field generating element enclosed in a tunnel excavating machine so that the element always faces the vertical direction, and providing magnetic-field detecting elements, wherein at least two intercrossing planes can be rotated vertically with respect to a horizontal plane, on a base plate on the ground surface. CONSTITUTION:A magnetic-field detecting element 14 is slowly rotated with a rotary shaft 16 as a center. Then the number of intercrossing magnetic fluxes cutting an intercrossing plane 15 of the magnetic-field detecting element is changed. An electromotive force induced in the magnetic-field detecting element 14 by the same alternating magnetic-field is changed. The direction at the minimum value, i.e., the direction of the magnetic-field detecting element 14 when the magnetic-field detecting element 14 and the magnetic-field are intercrossed in the least degree, is the direction where the magnetic-field element 2 is present. Now, three magnetic-field detecting elements 14 are rotated, respectively, and the intersection of the minimum- value directions is obtained. Ideally, the lines of the directions should be converged at one point. Generally, however, a small triangle is obtained. The position of the center of the triangle can be determined as the point directly over the magnetic-field generating element 2. It is not necessary to bring the magnetic-field detecting elements directly over the magnetic- field generating element. Therefore, even though the directly upper part of the magnetic-field generating element is located at the outer parts from the magnetic-field detecting device, the measurement can be performed.

Title: Overload detecting system for motor
Inventor: NAGAI TAKASHI
IPC: H02P25/10
Filed: 1992-02-14
Abstract: PURPOSE:To perform stop processing and to erase time accumulated before stoppage when overload current value of each motor is reset to a referential rated current value within a predetermined time. CONSTITUTION:Current transformers 39a, 39b... measure overload current values of motors 4a, 4b... and calculate overload rate. A time constant upto a stoppage is added according to thus calculated overload rate and if a level lower than a referential rated current value is detected continuously for a predetermined time during accumulated time of the time constant, the accumulated time is erased. Since a time constant is not added to a previous addition time if a level lower than a referential rated current value is measured under overload, each motor does not stop immediately upon occurrence of overload.
